ok what I would do is move the file shop.html into the folder zc then make you config file look like this.
PHP Code:
//if your mark up file is located in the same folder as this file.
#$zc_temp = DIR_FS_CATALOG . DIR_WS_TEMPLATES. 'sang_embed/common/' . 'FILENAME';
//if your mark up file is located in the zen cart root.
$zc_temp = DIR_FS_CATALOG . 'shop.html';
//other wise fill this in
#$zc_temp = 'http://mywebsite.com/shop.html';
